CASH-REGISTER.

Specification of Letters Patent. Patented June 20,1911.

Application filed November 25,' 1907. Serial No. 403,769.

To all whom it may concern:

Be it known that I. CARL Tees, :1 subject of the King of Prussia. and resident of Bielefold. in the Province of \Vestphalia. Ger

5 man Empire, have invented certain new and useful Improvements in Cash-Registers, of which the following is an exact specification. This invention relates to cash registers of the type which deliver printed vouchers for the quantity registered and is specially directed to those cash registers of this type which have separate printing mechanism for each operating level or row of keys. The vouchers corresponding to each lever orrow of keys may be distinguished by a particular color and thereby facilitate the addition or other clerical work to be carried out with them. It has already been proposed to deliver a number of unit vouchers of a particular kind corresponding to the integral numher, to which the lever was set or to the in tegral number of the ,key. Thus for a 96 cent bill, 9 separate 10fcentvouchers would be delivered and for a 9 dollar bill 9 sepa- '-rate 1 dollar vouchers would be delivered.

Accordin to the present invention a single T011518? will be delivered for each row of keys brought into operation or for each lever operated and this single voucher shall be printed with the number of units corresponding to the setting of the cash register, lever or key. Further only the printing mechanisms actually required are called into operation.

The invention is. illustrated in one convenient form in the accompanying drawings, which show a 'cash register with setting levers.

Figure 1 ,is a side view of a cash register with the cover plate and side plate removed a, and the printing and delivering mechanism in section. Fi 2 is a sectional elevation onthe line A B 0 Fig. 1. Fig. 3is a sectional elevation on the line C D of Fig. 1. Fi s. 3 and 3 show vouchers as'they would be elivered for a sum amounting to 0 dollars 50 cents; the vouchers are shown opposite their respective printin mechanisms. Fig. 4 is a frontview and i 5 is a section of the enaging pawl for the printing mechanism.

ig. 6 is a longitudinal section of the pawl. Fig. 7 is a detailed view illustratin the engaging mechanismfor operating the pawl. *ig.-'8 section through the engaging 56 niechanism shown-f in:Fig. Fig. 9.isa sectional View and Fig. 10 is a side view of the cam for operating the mechanism. Fig. 11 is a vertical section and Fig. 12 is a'partial elevation of the operating cam for the cutting mechanism.

Referring to Fig. 2 the levers a Z) 0 d are arranged in the. usual way to effect the registration of the amount purchased. These levers are fixed on concentric shafts a b c d, each of which carries a printing segment 57. Thus the printing segment on the shaft 0! may have tens of dollars-10, 20 30', 4.0 and 50, etc., while the printing segment on the shaft 0 may have tens of cents 10, 20, 30

and so on. The other two printing segments on the shafts b and d may have units of dollars and cents respectively. hen the various levers have been set to the amount to be registered, this'operation has the effect of putting the printing and voucher delivering mechanisms corresponding to said levers into operative conneption with the crank driven parts. This is effected by a cam opening 48 (Fig. 1). in the printing segments 57. In this cam opening there engages a roller 47 mounted on a lever 46 loosely mounted 011 a shaft 49. The lever 46 has a grooved end 35, (see also Figs. 7 and 8) in which there engages a pin 34; carried by a pawl31 (see Figs. 1 5 and 6). The pawl 31 is pivoted at 32 to a pin carried by a disk 30 (see Fig. 3). The disk 30 is fixed to rotate with an impression roller 29, which prints any desired names or advertisement on the voucher. The impression roller 29 may be defective as shown so as to deliver only a desired length of'st'rip corresponding to the length of the voucher.

It will be seen that the cam groove 48 causes the lever 46 to descend and thereb" the upper claw end 33 of the pawl 31 1S broughtto engage in a cut away part of a flange 27 provided .on asleeve 27 which is fixed to rotate with the shaft 25.

It will be seen that the coupling mechanism described is duplicated for each print ing mechanism so that each lever a b c (lis adapted by its operation to operate a differcontrolled levers 56, supported on a she t' -lit) 55 is provided for each in) ,ression roller 29. Above each impressionrol er is a rubber or like feeding roller 42, adapted -'to be frictionally driven through roughened or toothed disks 11 adapted to enga e with roughened or toothed disks 10 fixe to the impression-rollers 29.

The feeding rollers 42 are loosely mounted on pins 44, which are eccentrically supported in bearing brackets 43. An arm 15 is fixed to the eccentric pin stand by adjustin this arm the amount of pressure exerted Tiy the feeding rollers 12 on the impression roller 29 may be altered as will be readily understood. The strip to be printed by the impression roller 29 isguided to the said rollerby a guide channel 20.

After the lovers a b a (Z have been set, the operator tur'ns the hand crank 1. The hand crank 1 drives through the transmission wheels 2, 3, 4 and 5 the operating shaft 6 for the value printing and voucher cutting mechanism. On the shaft -6 there is keyed a cam 7 having a groove 7, in which there engages a roller 9. (See Figs. 9 and 10). The roller 9 is carried by a lever 10 keyed to a shaft 11.. To the shaft 11 there are also keyed the levers 12, which are connected by links 13 to a cross bar 14: guided in "ertical guides 15 in the .side frame plates of the machine (Fig. 2). The cross bar 14- carries stamps 16, one of which is arranged over each of the printing segments carried by the shafts a b c d respectively. The shaft 6 also carriestwo cams 8 (see Figs 2, 11 and 12), in which there engages rollers 17 carried by levers 18loosely mountedon the shaft 11. The levers 18 are extended toward the front of the machine, (see Fig. 1), and carry connecting rods 19, which are articulated to the sliding blocks 20, carrying the knives 21. The knives 21 cooperate with a cutting late 22 to cut off the desired length of vouc er, which is then delivered throu h an opening in the outer casing indicate in broken lines in Fig. 1. The shaft 6 is geared to the shaft-25 by wheels 23, 24 and 26. 'It will be seen therefore that, wheir'one or more of the lovers a I) c d have been set and the crank 1 rotated, the impression rollers corresponding to the levers set and owing to the engagement of the corresponding coupling pawl 31, are caused to rotate whereby the paper strip is fed forward. This strip is pressed bythe stamp 16 onto the uppermost type on the segment 57. This uppermost type of course corres ends to the setting of: the lever a b c (I, w iichever is or are operated.

So that those printing mechanisms, which are not set in engagement with the shaft 25, may not rotate b the frictional action of their.sleeves on te shaft, the pawl 31 is provided with a projecting pin 34, which.

in the position of rest of the pars i. 1!. with the pin 34 in the groove 35 of the lever 46, the projecting part of the in.34,'rests in a notch 36 on a plate 36, w ich is held from rotation by a lever 39 carried by a shaft 38.

Toothed wheels and '61 are arranged to transmit rotary motion froin the shaft 25 -to a cam shaft 53. Thecam I13 works in a cam opening in a lever 52 having a forked end engaging in a pin 51" on a. lever 51.

The lever 51 carries an inking ad'54. Of coursean inking pad is. provi ed for each segment. In Figs. 1 and 10 it will be seen that the cam groove 7" is so shaped that the Y stamp 16 will be first lowered (assumingthe crank 1 to be rotated clockwise in Fig. 1) a small amount andthen a greater amount.

The first short descent of the stamp is effected when'the inking pad is over the seg-.

descends and severs the voucher from the strip. It will 'be seen, that, if the crank 1 is rotated without previously setting the levers a (2 0 al, no voucher will be delivered as none of the rollers 29 would in that case be operatively connected to the shaft 25.
